MINE CAR 7 Filed Aug. 20, 1950 I'll .belts or bandswhich extend entirelyPatented Nov. 1, 1932 WILBUR D. HOCKENSMITH, 31%., OF IRWIN,PENNSYLVANIA 7 time CAR Application filed August 20, 1930. 7 Serial No.476,508.

This invention relates to mine cars and more particularly toimprovements in the construction thereof. The standard mine car inexistence at the present time comprises a floor, flaring side floorsextending from the floor and side walls riveted to the side floors. Thecar is tied together and reinforced by around the car. The belts arerelatively thick (usually one inch) in comparison with the thickness ofthe side walls (usually about onequarter of an inch). A mine car builtwith the belts around the outside has a limited capacity in relation toits overall width and length, that is the inside width is at least twoand one-half inches less than the overall width. In mining where spacein which to work is usually limited and the entries in the mine are of'relatively narrow width, it is 11ecessaryto provide a car having amaximum load capacity with a minimum height for easy loading and aminimum width to insure suflicient clearance between the sides of thecar and the sides of the entry. The use in mining 2 of cars having arelatively small load capacity materially increases the cost of mining.

One object of this invention is to provide a mine car having anincreased load capacity without increasing the overall dimensionsthereof.

Another object of this invention is to provide a mine car having beltsor bands on the inside of the side walls of the car.

A further object of this invention is to provide a mine car in which theend gate is fastened to a triangular plate pivoted to the outside of thecar.

A still further object is to provide a mine car in which the reinforcingbelts or bands are completely inside the side wall and the side floorsof the car.

These and other objects, which are readily apparent to those skilled inthis particular art, I attain by means of this invention, one 4embodiment thereof being described in the following specification andillustrated in the accompanying drawing, in which:

Figure 1 is a side elevation of a mine car embodying this invention.Fig. 2 is a partial end View of said car having a portion thereof cutaway to show the construction. Fig. 3 is an end view of this car.

Fig. 4 is a partial end View disclosing a modified form of construction;and

Fig. 5 is a partial View in section disclosing a modified form ofconstruction.

In the drawing, 1 have illustrated'a mine car of the standard type inwhich a floor 1 is provided, which is composed of three planks extendinglengthwise of the car. The floor is braced by T-shaped bars 2 which areplaced between the planks. The T portion of the bar is countersunk inslots provided in the planks. The floor 1 is shown suspended from axles1 which are enclosed inlishaped housings 5 having laterally extendingflanges '6 thereon. Bolts 7, extending through the floor, secure thefloor to the flanges ii of the housing. The axles 4 may be stationarywithin the housing 5 or they may turn with the wheels. In the lattercase, the housing is provided with bearings (not shown) which supportthe axles. Wheels 8 are journalcd on the ends of the axle on each sideof the car. Angle irons 9 extend the full length of the car on each sideof the floor and form side sills for the car.. Plates 10, havingoppositely disposed flanges 11 and 12 along the edges thereof, :formside floors for the car. The flange 11 is riveted to the angle iron 9and plates 13 which form the side walls for the car are riveted to theflange 12. The side walls and side floors are reinforced and tied to theother parts of the car by reenforcing .members or belts 14, which extendentirely around the car. In my improved type of construction, I placethe belts 14 on the inside of the side walls 13 and underneath the sidefloors 10. Openings 15are provided in the side floors 10 through whichthe belts ll are extended. The belts are riveted to the side walls andside floors and bolted to the floor 1, so that the planking may bereadily changed. The belts are countersunk in the floor 1 to obtainsufficient clearance between the bottom of the car and the rail, forotherwise larger wheels would have tobe used to obtain a given clearanceand, therefore, the

overall height would have to be increased to obtain a given capacity.

By placing the belts 1 L inside the side wall, I have increased the loadcapacity of the car without increasing the overall width thereof. Thisconstruction also permits the use of a different type of bailor gatelift than is commonly used, which materially reduces the overall widthof the car. In building my car, I provide a gate 16 of the usual typefor closing the end of the car, which is fastened along the sidesthereof to triangular plates 17 (one of which is shown). The plate 17 ispivoted at 18 on the side 13 of the car. The plate 17 forms the bail orlift for the gate 16. The pivot 18 is reinforced by a plate 19 rivetedto the inside of thecar. The placing of the belts inside the side wallsleaves the outside of the wall relatively smooth and free fromprojections, making it possible to place the plate 17 very close to theside wall and by using a relatively thin plate for a bail instead of theordinarily used relatively thick bar, the overall width of the car ismaterially reduced.

In Fig. 4, I have shown a modified construction of a mine carin whichbelts 20 are placed on the inside of the car adjacent the inside ofwalls 13 and the side floors 10 and underneath the floor 1. The sidefloors 10 are provided with openings 21 adjacent the side sills, throughwhich the belts 20 extend. The belts in this modification extendentirely around the car and are countersunk in the floor 1. The end gateand the lifting .bail are exactly similar to those already described. Itis readily apparent that by placing the bands orbelts inside the sidewalls of the car, the inside width is increased by double the thicknessof the bands, while the overall width of the car remains the same. Inthe modified form, the load capacity is further increased when the beltsare placed inside the side floors as Well as the side walls- Myinvention is also readily applicable to other types of mine cars such asan all steel car, wherein the belts or bands are in sec tions and do notextend entirely around the car. In Figure 5 I have partially shown a carhaving the belts in sections. In such cars the side sills arecomparatively heavy and sufficient reinforcement for the car can beobtained by riveting the .belts directly to the side sills. In Figure 5,belts 30 are riveted to the inside of the side wall 31 and may beriveted to the inside or outside of the side floor 32 as in the otherembodiments of my invention. The ends of the bands are riveted to, aside sill 33. Mine cars, when in use, bump against each other and aresubjected to severe shock. For that reason it is desirable to have thefloor of the car constructed of relatively thick planks, the ends ofwhich protrude beyond the ends of the body portion and act as bumpersfor the car. The

floor, and

body of the car is usually bolted directly to the floor boards and theshock of bumping is taken by the bolts. By countersinking the belts inthe floor I am able to use a thicker plank floor than otherwise andobtain the advantage of the larger bumping area without encroaching uponthe capacity of the car. Also the belts are madeto fit snugly in thegrooves in the floor boards and the edge of the belts gives added areain addition to the body bolts for absorbing the shock of bumpingencountered in usage.

While I have illustrated an end dump car having the. fioor suspendedfrom the axle, it is readily understood that my invention can be appliedto any type ofcar, such as cars having the floor above the axles, andcars of the rotary dump type. It is also readily apparent that certainomissions, additions and substitutions may be made in this applica-.

tion without departing from the spirit and scope of the appended claims.
